+
+功能：
+这个函数用于检测是否有鼠标点击事件发生并立即返回。
+当执行该函数并且检测到鼠标点击事件后，执行delay_fps/delay_ms/delay_jfps函数会清除鼠标点击状态。
+
+声明：
+
int mousepressed();

+参数：
+（无）
+
+返回值：
+如果有鼠标点击发生，返回 1；否则返回 0。
+
+示例：
+#include 
+
+int main() {
+	initgraph(800,600);
+	setrendermode(RENDER_MANUAL);
+	
+
+	int count = 0;
+	for(;is_run();delay_fps(60)) {
+		if (mousepressed()) {
+            //检测到鼠标点击事件
+			count += 1;
+            //清除屏幕原有内容，然后输出点击提示
+			cleardevice();
+			xyprintf(50,50,"clicked %d times",count);
+		}
+	}
+	closegraph();
+	return 0;
+}
